MICHAEL DANAHER, OF BUFFALO, ILLINOIS.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 328,764, dated October 20, 1885.

Application filed May 11, 1885. Serial No. 165,091.

To all whom it may concern:

Be it known that I, IVIICHAEL DANAHER, a citizen of the United States, residing at Buffalo, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Corn-Planters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a plan view. Fig. 2 is a vertical section on line 00 m, Fig. 1. Fig. 3 is a detail View.

This invention has relation to check-rower corn-planters; and it consists in the combination of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

Referringby letter to the accompanyingdrawings, A designates a corn-planter of the class in which two opening'shoes, B, and two reciprocating seed-slides, O, are employed,and are operated by a check-rope, which is stretched across the field and provided with knobs or balls which engage the arms D of a rockshaft, E. These arms D D are provided with forks D at their upper ends, which engage the knobs or balls F long enough to operate the seed-slides to draw them forward. The rock-shaft E is also provided with arms G G intermediate of the arms D D, which arms D D have eyes D at their lower ends, which are connected by links F to the forward ends of the seed-slides 0, so that when the forks D engage the knobs or ball F said arms will move backward and operate the rock-shaft E to move the seed-slides G forward,and thereby cause the seed to be dropped.

Pins or studs H are provided in the upper faces of the seed-slides 0, near their forward ends,to which the links F are connected.

A spring, I, extends from slide to slide and engages astud, I, in the middle bar, 1 ,01 the frame which carries the opening-shoes B.

(No model.)

The ends of the spring I are curved slightly rearward and engage studs H in the upper faces of the seed-slides 0, near the forward ends of the same. The action of the spring I is to return the seed-slides to their normal positions after they have been operated to drop the seed.

The seed-hoppers are of the ordinary construction, with a discharge opening in the bottom,beneath which the seed-slide is reciprocated by the rock-shaft when operated.

The main frame, which is supported on riding wheels, is provided with middle parallel bars, M M, having a space,M,between them. An inclined arm, N, having a slot, N, has a friction-roll, N mounted in bearings secured to the under face of the arm. This frictionroll N has its middle diameter, N made the greatest, and this largest portion rides between the parallel bars M M, the next smaller portions forming the riding bearing and the smaller portions forming the journals.

A T-head bolt,P, having its head P bearing against the under face of the parallel bars MM, holds the inclined faceQ of the inclined arm N in place, and permits the seat to be adjusted forward or backward at pleasure. By this arrangement the drivers weight can be utilized to relieve the horses necks of the weight of the tongue of the machine. The forks D, which engage the check-rope, are provided with snaps S, to hold the rope in place, and friction-rollers S, to lessen the friction on the rope or wire when the machine is operated.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination, with the frame having the middle parallel bars, M M, with space M between them, of the inclined slotted arm having the seat, the bolt with bearings, and the friction-rolls N in said slot, and the T- head bolt and wring-nut connecting the parallel bars and the inclined slotted arm, substantially as specified.

2. The combination, with the seed-receptacles and opening-shoes, of the check-bar having arms connected with the feed-slides,

forks at their upper ends, and the spring I, In testimony whereof I affix my signature in 10 extending transversely of the frame and pen presence pftwo nwitnessesn, gaging the stud I, of the bar I, and the studs. H of the feed-slides, substantially as specified. MICHAEL DANAHER.

3. The combination, with the check-bar, of I the forked arm D, having the roller S, and Witnesses: the clasp S, arranged in the said fork, the LEWIS GRUBB, Whole adapted to operate in a seed-planter, JOHN N. LONG. substantially as set forth.
